Appendices to Twenty-first Annual Report 



The one steady run of fish in the Nith is shown by the sea-trout curve. 

 This begins in the middle of April and continues till the end of June. 



It may very well be that the three isolated runs shown in July, when 

 salmon, grilse, and sea-trout occur simultaneously, are accounted for by 

 suitable conditions of water-flow occurring in the river otherwise reduced 

 to summer level, but the spasmodic condition of the salmon curve 

 throughout the season seems to point, undoubtedly, to a seriously reduced 

 condition of the fishery.
